Many airlines suspend live animal cargo transport during the hottest months of the year. This guide covers carrier policies, temperature cutoffs, cabin alternatives, and planning tips for pet owners travelling or relocating in summer 2026.
Key Takeaways
- Most major airlines enforce seasonal cargo embargoes for live animals between May and September, with some extending into October.
- Temperature cutoffs typically range from 80°F to 85°F (27°C to 29°C) at any point in the journey: origin, transit, or destination.
- Brachycephalic (flat faced) breeds face stricter limits year round and are often banned from cargo entirely.
- In cabin travel for small pets remains available on many carriers throughout summer, making it the most reliable warm weather option.
- Planning at least 8 to 12 weeks ahead is strongly recommended for summer relocations involving pets.
Why Airlines Suspend Pet Cargo in Summer
Each summer, airlines around the world temporarily halt or restrict the transport of live animals in cargo holds. These seasonal embargoes exist because cargo areas, tarmacs, and ground handling zones can reach dangerously high temperatures during loading, transit, and unloading. Even climate controlled cargo compartments cannot fully protect animals from extreme heat exposure on the ground, where pets may sit in crates on open tarmac while waiting to be loaded or transferred between flights.
Veterinary guidelines consistently identify heat stress and heatstroke as leading causes of in transit pet emergencies. According to the U.S. Department of Transportation, airlines are required to report animal incidents, and heat related events spike sharply during summer months. The embargoes are a direct safety response to these risks.
Which Airlines Suspend Live Animal Transport in Summer 2026
American Airlines
American Airlines Cargo typically embargoes warm blooded pet shipments from, to, or through certain high temperature stations from May 1 through September 30. The airline will not transport warm blooded animals when the ground temperature at any point in the journey (origin, connection, or destination) exceeds 85°F (29°C) or falls below 45°F (7°C). Below 45°F, an acclimation certificate from a veterinarian may be required.
Delta Air Lines
Delta places an embargo on pets as checked baggage from May 15 through September 15. The airline will not accept pets in cargo when the forecast ground temperature exceeds 80°F (27°C) at any point on the route. For brachycephalic breeds, the threshold drops to 75°F (24°C). Between 20°F and 45°F, a veterinary acclimation certificate is required. Delta does offer its Summer Live Animal Program through Delta Cargo (typically May 15 to October 15), which uses climate controlled vans for ground transport and can lift some of the standard temperature restrictions for an additional fee.
United Airlines
United Airlines has limited its general public cargo pet transport significantly in recent years. The PetSafe programme has faced periodic suspensions, and cargo transport currently remains restricted to qualifying military personnel and U.S. State Department orders in many cases. Regardless, United enforces seasonal embargoes from May 1 through September 30 for travel to and from extreme heat destinations such as Las Vegas, Palm Springs, Phoenix, and Tucson. Pet owners should verify availability and restrictions directly with United well before booking.
WestJet Cargo
WestJet Cargo embargoes all live animal shipments, including its Pet Air service, to and from designated cargo stations from May 15 through October 31. This is one of the longer embargo windows among North American carriers.
Middle Eastern Carriers: Emirates, Etihad, and Qatar Airways
For pet owners in the Gulf region, summer presents particular challenges. Emirates and Qatar Airways do not permit pets in the passenger cabin at all; animals must travel as cargo. Etihad allows small pets (up to 8 kg including carrier) in cabin on flights to and from Abu Dhabi. Across all three carriers, brachycephalic breeds are typically only accepted as manifest cargo from October through April, making summer transport extremely limited. Ground temperatures in the Middle East routinely exceed safe thresholds from May onwards, and owners relocating from the UAE should plan departures for early spring or late autumn whenever possible.

Temperature Cutoff Policies: A Carrier Comparison
While specific policies vary, the following temperature thresholds are commonly applied across major carriers:
- Upper limit (standard breeds): 80°F to 85°F (27°C to 29°C). If the forecast ground temperature at origin, any connection, or destination exceeds this range, transport is refused.
- Upper limit (brachycephalic breeds): 75°F (24°C) or lower, depending on the airline. Many carriers ban flat faced breeds from cargo entirely year round.
- Lower limit: 20°F ( minus 7°C) for most carriers. Between 20°F and 45°F, a veterinary acclimation certificate is typically required.
- Acclimation certificates: Issued by a licensed veterinarian, these confirm that a specific animal can safely tolerate a given temperature range. They are usually valid for a limited window and must be presented at check in.
It is important to understand that these thresholds apply to forecast conditions at the time of travel, not just current conditions at departure. A flight departing from a cool climate but connecting through a hot hub can still be refused.
Breeds at Higher Risk
Brachycephalic (short nosed) dog breeds such as Bulldogs, Pugs, Boston Terriers, Shih Tzus, and Boxers, along with flat faced cat breeds like Persians and Himalayans, face significantly greater risk during air cargo transport. Their compromised airways make it harder to regulate body temperature under stress, and many airlines have permanently banned these breeds from cargo holds regardless of season.
If you own a brachycephalic pet and are planning summer travel, in cabin transport or ground alternatives are strongly recommended. A veterinary consultation is essential before any air travel with these breeds.
Cabin Alternatives for Small Pets
In cabin pet travel is not subject to cargo embargoes and remains available year round on most pet friendly airlines. This makes it the most dependable option for small pet owners during summer.
Top Cabin Friendly Airlines
- Alaska Airlines: Accepts dogs, cats, and rabbits in cabin. Carrier must fit under the seat (maximum approximately 17 by 11 by 9.5 inches).
- Delta Air Lines: Small cats and dogs in soft sided carriers that fit under the seat. Clear booking process and transparent rules.
- Southwest Airlines: Flat rate in cabin pet fare. Small cats and dogs permitted. No cargo or checked pet options available at all, which simplifies planning.
- JetBlue: In cabin pet programme for small dogs and cats. Known for clear communication about pet rules.
- JSX: Announced that pets up to 30 kg (66 lbs) will be accepted in cabin on designated large pet friendly scheduled flights, with availability expected for summer 2026. This is a notable development for owners of medium sized dogs who typically have no cabin option.
- Etihad Airways: Small pets up to 8 kg including carrier on flights to and from Abu Dhabi.

Cabin Travel Tips for Summer
- Book early. Most airlines limit the number of pets per flight (often two to four).
- Choose early morning or late evening flights to reduce heat exposure during ground handling.
- Use a well ventilated, airline approved soft carrier. Freeze a small water bottle to place inside.
- Carry a portable water dish and offer water frequently before and after the flight.
- Avoid sedation unless specifically prescribed by a veterinarian for your pet. Sedation can impair thermoregulation.
Ground and Sea Alternatives
When cargo embargoes block air transport and your pet is too large for cabin travel, ground and sea options deserve serious consideration.
- Professional pet transport services: Companies specialising in door to door ground transport use climate controlled vehicles and allow regular rest stops. These services are widely used for domestic relocations in North America and Europe.
- Personal vehicle travel: Driving offers complete control over temperature, rest breaks, and your pet's comfort. For tips on safe travel with dogs, our Off Leash Spring Hiking With Your Dog guide includes advice on road trip hydration and rest planning.
- Amtrak (U.S.): Permits small dogs up to 20 pounds on trips of seven hours or less for a modest fee.
- Transatlantic sea crossings: Cunard's Queen Mary 2 offers onboard kennel facilities for transatlantic voyages, making it one of the very few ocean crossing options for pets.
Planning Ahead: A Timeline for Summer Pet Relocation
12 Weeks Before Travel
- Research airline policies for your specific route and pet type. Contact the airline directly to confirm current embargo dates.
- Schedule a veterinary health check. Many countries require a health certificate issued within 10 days of travel, plus up to date vaccinations and microchip verification.
- If relocating internationally, confirm import requirements for the destination country, including quarantine rules and breed restrictions.
8 Weeks Before Travel
- Book flights and pet reservations. For cabin travel, call the airline to add your pet, as online booking for pets is not always available.
- Order an IATA compliant crate if cargo travel is confirmed, and begin crate training immediately. A pet that is comfortable in its crate will experience significantly less stress in transit.
- Arrange veterinary documentation: rabies titre tests (if required), acclimation certificates, and any destination specific paperwork.
4 Weeks Before Travel
- Confirm all bookings and recheck the airline's embargo status. Policies can change with short notice based on weather forecasts.
- Ensure your pet's microchip is registered and that your contact details are current.
- If boarding your pet before or after travel, research facilities early. Our guide on Holiday Dog Boarding: How to Choose the Right Facility covers what to look for.
1 Week Before Travel
- Obtain the final veterinary health certificate (within the required validity window for your destination).
- Confirm the weather forecast for all segments of your journey. If temperatures are borderline, have a backup plan.
- Pack a travel kit: water, collapsible bowl, familiar blanket, waste bags, copies of all documents, and any prescribed medications.
When to Seek Veterinary Help
If your pet shows signs of heat stress during or after travel, including excessive panting, drooling, lethargy, vomiting, unsteady movement, or collapse, this is a veterinary emergency. Move the animal to a cool area, offer small amounts of water, apply cool (not ice cold) water to the paws and ears, and seek immediate veterinary attention.
Veterinary professionals recommend that any pet with a pre existing respiratory condition, heart disease, obesity, or advanced age should receive a thorough fitness to fly assessment before summer travel is considered. For senior dogs with joint conditions, summer heat compounds the stress of travel; our Senior Dog Arthritis: Spring Walk Guide discusses how temperature and activity interact with mobility issues.
Final Recommendations
Summer cargo embargoes are not obstacles to resent; they are evidence that the airline industry takes animal welfare seriously during high risk conditions. Pet owners who plan ahead, understand carrier specific policies, and explore cabin or ground alternatives will find that safe summer travel with pets is entirely achievable.
The single most important step is to start early. Confirm policies directly with your chosen airline, consult your veterinarian, and always have a contingency plan. Embargoes can shift, weather can surprise, and flexibility is the pet traveller's greatest asset.
